Please comment and subscribe. If you've finished seeing the pictures let's move on to the building part shall we?

Step 1: Motor Attachment

This section obviously holds the motor. Watch carefully for those little tan y connectors. They are pretty hard to see.

Step 2: Hill Base

What hill is complete without a base? Make this easy thing which will be supporting the tubes attached to the hill.

Step 3: Hill Support

This is the first time you'll be using tubes. Pay close attention to the pictures and the image notes.

Step 4: Hill

OK now you have made the hill base and the hill support. Now it's time to build the hill. Pictures 8-11 are the part that is gonna attach to the track. Attach it as close to the middle of the lift as possible.

Step 5: Turning Drop Support

This support is for the turning drop right after the crest of the coaster. Pay close attention to how the pipes are built.

Step 6: Loop Support Part 1

This section is the side of the loop where the car comes in. The pipes will attach to the track when you add the track.

Step 7: Loop Support Part 2

this support holds the pullout of the loop. I will get better pictures of the pipes next time.

Step 8: Barrel Roll Support

Here's the support for the barrel roll. None of the pipes are difficult to build. Just make sure the pipes are in the right positions.

Step 9: Curve Support

This is the last step where you have to make pipes. After this you'll just be track and chain.

Step 10: Attaching the Track

Now it's time for the fun part of the roller coaster. The track!! Pay attention to the chain guides and the track guide.

Step 11: Attaching the Chain

Last step. Now you just have to attach the chain and your done. Make sure that the chain runs on the chain guides. You should use 179 chain links.

Step 12: Your Done!!!

Congratulations!! You've completed Electric Eel! Now turn the motor on and watch the cars zoom through the track. Enjoy!!! :-D
how you connect your roller coaster ?
I use the connectors that come in the older sets

<p>bro that was 5years ago lol</p>
<p>what woudl be the total cost for this</p>
<p>Under $30, from a guess</p>
<p>I sooooo want to build this, just am creating a new coaster, which used all of my parts, I ran out of my most abundant part, the blue rod v: </p>
<p>I built this over and over!!!</p>
This is amazing!! It's a great little Knex roller coaster I built in my room. The only part I skipped was the stuff that goes outside the track, besides on the drop. If you have the time and pieces, build this
<p>Brilliant coaster - took me a long time to build though XD! I now need the track!</p>
Thank you so much! This was my first coaster I ever really made and it started my love for knex. Now I am building my own creations and love building! I have a vid of this when I made it on YouTube and gave you full credit and recommended you
do you got have 2 car train?
you could try with any amount! Go for it!
Hey check out &quot;Formula 1&quot; coaster <br>
It is the most nice coaster and esy but its still long to do;)<br><br>AWSOME!!<br><br>***** Star
no more knex and purple conector i can not continue :(<br>
unlucky man. :(
Because yours, Burrito Masters bballer347's etc. coasters are so great how long did this one take?? because when i try i get to the top of the lift and its not good so i take it down i guess i just want to finish in one night
Believe me when I say that you need a lot of patience to build coasters. This one took a couple days to complete but these days it takes me at least a month. If you want a good crest (top of hill you should just remember to put the gear as clos to the track as you can.
ok then thnx <br>
No prob! Looking forward to seeing your coaster. Do you build micro or normal pieces.
Please help me! i have all the pieces, but im having trouble trying to build the first support on this section D: i don't understand it, please reply :(
How many tracks it takes ? Because i have 26
Uses 14. You should be good! :)
awsome! i have a whole bunch of micro knex but i dont have the track. its still awesome!<br>
Its awesome
i agree
thanks! :-P
how do you attach the 2 cars together?
The easiest way is to cut a rubber band into two pieces tie TWO knots into each end and fit them into the holes under the cars.
Ta very much, nice coaster by the way
No prob! Thanks!
Nice :)
Thanks. <br>
No prob! But use the reply button next time ;-)
Tornado 96,how many track pieces do you need to build this,I'm working on the piece count right now cause I might build it but that was the only thing I was unshore about.
I think it's 14 pieces of Normal track not half track.
I'm now starting a Micro Knex coaster for the Winter Contest!<br>
Sweet! :-)
I already made a system that I can use one chain for lift, station and brakes!
Wait why do you need brakes? and post it on SSC please :-)
When I finished the lift It'll be posted :-) I just like brakes, they upper realism.
